Definitions

  • the present invention relates to a disposable absorbent article, more specifically a disposable absorbent article comprising three or more longitudinal panels separated by channels and capable of a generally reciprocal pivoting movement, thus providing a product dynamically adaptable to the user's body and able to quickly absorb the body fluids released on it.
  • Disposable absorbent articles are consumption articles widely known in the state of the art. Typical examples are diapers for children and incontinent adults, women's napkins, bandages for wounds, breast protectors for mothers in the milk-feeding phase, sweat absorbers, and the like.
  • women's intimate napkins (generally referred to as “women's napkins” or even merely as “napkins”), the object of the preferred embodiment of the present invention, are disclosed and described without excluding the protection of any other type of disposable absorbent article the features of which are inserted in the scope of the invention and claimed in the end of this specification.
  • top layer and the “coating layer” which are comprised in absorbent articles known in the state of the art.
  • the known absorbent articles comprise an absorbing core sandwiched between two so-called top layer and coating layer.
  • the top layer which is usually flexible and fluid permeable, is designed to contact the user's body, and aims at allowing the flow of the body fluid towards the absorbing core.
  • it is a non-woven layer or perforated plastic film.
  • the coating layer is impervious or resistant to the flow of fluids and is designed to prevent the fluid from leaking from the absorbing core which could otherwise contaminate and dirty the user's clothes. In a quite common way, it is a thin non-perforated plastic layer.
  • the top layer and the coating layer can be single or composed of more than one material having one or more coats, and typically its dimensions are a little higher than those of the absorbing core between them, so that they are joined (glued, adhered, sealed, welded, sewn, or by any another means known in the state of the art) to one another along its perimeter.
  • absorbing core another element known by those skilled in the art.
  • it is comprised of cellulose fibers, paper coats, polymeric fibers, superabsorbent materials (for example, acrylate based particles or fibers which produce gel when in contact with humidity), turf moss, combinations of those materials with one another, and the like. Its purpose is to absorb and retain the body exudates, for example blood, urine, milk, sweat, etc.
  • side edges or simply “sides”
  • longitudinal ends or simply “ends”. They are references to the peripheral parts of an absorbent article, where “side edges” are the edges parallel to the length of the absorbent and “longitudinal ends” are the tips or ends transversal to the length of the absorbent.
  • upper face of the absorbent refers to the face facing the user's body and “lower face” means the face opposing the higher one facing the user's clothes.
  • Still another example in the state of the art of a more anatomical shape is the provision of a protuberance in the central region of a woman's napkin, in such a way that the absorbent material is close to the site the menstrual fluid is discharged.
  • U.S. Pat. No. 5,057,096 (Francis Faglione) and patent document EP249405 (Smith & Nephew Assoc. Co. PLC) are examples thereof.
  • U.S. Pat. No. 5,591,148 discloses a woman's napkin comprising an absorbing core consisting of three longitudinal absorbing panels, the central panel being more prominent and supported on an element that acts as a spring to keep it at a higher position, therefore closer to the user's vagina during the use. It is a product of a complex and expensive construction, different from the one of the present invention.
  • U.S. Pat. No. 5,695,324 discloses a woman's napkin provided with two absorbing cores, one vertically positioned with relation to the other, the aim of which is a partial penetration in the great lips of the user's genitalia. There are no joints between any of the absorbing cores, in such a way that the displacement of on affects another one, different from the present invention.
  • the present invention provides an improved alternative of the state of the art through the provision of a disposable absorbent article of simple and cheap construction, propitiating a dynamic and static adaptation to the user's body, concomitantly with an optimized fluid absorption.
  • the present invention is directed to a disposable absorbent article characterized by comprising an absorbing core provided with three or more substantially independent absorbing panels, longitudinally oriented and separated in the transverse direction by channels, and joining means between said absorbing panels.
  • three independent, parallelepipedical parallel panels of cellulosic fiber of wood pulp constitute the absorbing core of a woman's napkin.
  • the bases of the three absorbing panels are affixed to a liquid impermeable coating layer, and a liquid permeable top layer wraps the remaining part of its surfaces.
  • the top layer is sealed to the coating layer between the bases of the adjacent absorbing panels, along a longitudinal line or band. This sealing generates a joining means that allows for the pivoting of one panel in relation to another adjacent panel.
  • the external faces of the absorbing panels are wrapped by the top layer, and said same top layer is sealed to the coating layer in the space existing between each panel, a slot or channel is generated between every two adjacent panels.
  • the two side absorbing panels can pivot in relation to the central absorbing panel, being laterally conformed to the geometry of the space existing between the user's legs.
  • the channels allow the absorption along the whole extension of the body-facing upper surface of the absorbing panel, but also along the exposed side faces of the adjacent absorbing panels, besides serving as a reservoir and longitudinal directing means for the fluid towards the napkin ends.
  • the absorbing core of the woman's napkin of the invention comprises absorbing panels which are “substantially independent in the transverse direction”, wherein this expression denotes a sufficient physical separation in the direction transversal to the length, mainly in the central third of the article, for allowing one panel to pivot in relation to another one.
  • a continuous absorbing core contrary to that of the present invention, does not allow such movement, for the intrinsic flexibility of a continuous length of absorbent material does not allow for the pivoting in the sense of this invention.
  • the present invention can encompass embodiments wherein embossed lines are used and they are perforated, segmented, partially disrupted or otherwise submitted to a mechanical or chemical treatment that can eliminate or minimize the intrinsic rigidity, thus allowing an absorbing region to pivot in relation to an adjacent one.
  • the present invention also encompasses adjacent absorbing panels which, despite being provided with a common absorbing and/or structural base, can pivot in relation to another one.
  • the absorbing core comprises three or more absorbing panels.
  • an odd number of absorbing panels is used, thus defining a central panel that stays closer to the great lips of the vulva and tends to be inserted therebetween, thus diminishing the possibility of leak.
  • the woman's napkin of the invention comprises three to five absorbing panels, and still more preferentially only three.
  • the absorbing panels of the absorbing core of the invention are “longitudinally oriented”, that is, generally they follow the orientation of an imaginary longitudinal axis parallel to the length direction of the absorbent article.
  • said absorbing panels are substantially parallel to said imaginary longitudinal axis, but configurations wherein one or more absorbing panels show some inclination, for example, between 10 and 40 degrees with relation to the longitudinal, are not excluded. Still preferably, the absorbing panels are parallel to one another.
  • the absorbing panels of the absorbing core of the present invention are “separated by channels”, that is, there is a substantial physical discontinuity of a panel in relation to another adjacent one, and the space between a panel and another one is deemed to be a channel which can have a varying geometry (mainly with respect to the cross-section area) during the use of the napkin, when a panel is moved in relation to the others, typically pivoting like two halves of a hinge. Any other geometry, volume or orientation of said channels are not excluded.
  • the absorbing panels of the absorbing core of the present invention comprises “joining means” among themselves. That means that there is a means, construct or arrangement between one absorbing panel and an adjacent absorbing panel that allows one panel to pivot in relation to the other.
  • the pivoting of a panel or absorbent region in relation to another is the one that occurs in a similar way to the rotation of the halves of a hinge, one in relation to the other, without the occurrence of any substantial physical change (discontinuity, partial disruption, wrinkle, and the like) of the absorbent material involved.
  • the joining means is provided as a sealing joint (line, band, points, etc.) of the top layer over the coating layer, between adjacent absorbing panels.
  • the joining means can be situated close to any region along the thickness of the absorbing panels, and is preferably situated close to the base of said panels.
  • the joining means can have any extension, and is typically between 30% and 100% of the length of the absorbing panels.
  • the rotation of an absorbing panel in relation to the other is preferably between about 10 degrees about 180 degrees, and more preferably between about 15 degrees and 120 degrees.
  • the material of the joining means between adjacent absorbing panels allows the expansion, for example, flexible, elastic or corrugated material, thus allowing a higher absorption of the tensions imposed to the absorbent article of the invention.
  • said material would be foams, corrugated plastic films, crimped non-woven material, films with elastic zones in the region of the channels, etc.
  • the base of said channels placed between the absorbing panels is the joining means itself, and is preferred that the joining means is composed by the association of the top layer with the coating layer.
  • the joining means is comprised only by the top layer, or only by the coating layer, or still by the association of a distinct construct of two layers with one layer, or with another one, or both, or still any other arrangement that allows an absorbing panel to pivot in relation to another adjacent panel.
  • the multiple absorbing panels of the absorbing core of the invention can have identical or distinct conformations among themselves.
  • there is a bigger central panel which is thicker, (i.e. having a greater caliper) and is thus more protruding than the other adjacent panels to, as already mentioned, tend to perform a vaginal penetration and thus diminish the possibility of leaks.
  • the central absorbing panel is provided with structure which can be made conformable by filling the absorbing panel with from about 5 to 75% by volume of spheroidal elements having a diameter in the range between 0,1 mm and 5 mm, the spheroidal elements being confined in a recess of said absorbing panel or a closure distinct from the absorbing panel and inserted therein.
  • Suitable spheroidal elements include, but are not limited to polymeric beads such as polystyrene beads.
  • the absorbing panels of the article of the present invention in particular the central absorbing panel, comprise fluid pockets, for example air.
  • one or more pockets filled with air are incorporated the into the article to transmit a feeling of a higher initial thickness to the users who feel apprehended before using a thin product to absorb their menstrual fluid.
  • the cross-section of the absorbing panels retains the same area and geometry throughout its length, but alternatives with geometric changes along its length are not excluded.
  • the geometric shape of the cross-section of the absorbing panels of the invention can be any one, and can not be same for all the absorbing panels.
  • some advantageous examples can be cited (the sequence below refers to shapes of the cross-section of the side panel, the central panel and the other side panel, respectively):
  • the channels between the absorbing panels are preferably straight and have advantageously a constant minimum width close to the joining means, between about 0.5 mm and about 10 mm, preferably between about 2 mm and 6 mm.
  • a constant minimum width close to the joining means between about 0.5 mm and about 10 mm, preferably between about 2 mm and 6 mm.
  • one or more absorbing panels are fully wrapped by the permeable top layer, and this way they are joined (welded, glue, or by any another adequate means) on a coating layer that preferably, in this situation, also performs the function of a joining means.
  • the absorbing panels are fixed directly on the coating layer, but also it is encompassed in the scope of the invention the alternative where the panels are fixed to an intermediate construct (for example, foam, one or more thin layers of absorbent material of the paper or non-woven type, plain or corrugated material to facilitate the pivoting, etc.) which in turn is attached to or associated with the coating layer.
  • an intermediate construct for example, foam, one or more thin layers of absorbent material of the paper or non-woven type, plain or corrugated material to facilitate the pivoting, etc.
  • the absorbing panels which make out the absorbing core of the invention are typically separated, in the transverse direction, by longitudinal channels that run from a longitudinal end to the opposite one, in such a way that the absorbing panels have not absorbent material in common.
  • the absorbing panels are connected to one another by a transverse band of absorbent material; in other words, the channels are interrupted before reaching the longitudinal ends, without affecting substantially the pivoting capacity, that is, the dynamic conformation of the woman's napkin of the invention.
  • said transverse band of absorbent material in the longitudinal ends is between about 1 and 3 cm wide.
  • the central absorbing panel in the longitudinal ends of the channels, can alternatively be provided with transverse embossed lines that run from one channel to the next channel, in such a way to generate a trend of a better distribution of the fluid in the transverse bands of absorbent material in the longitudinal ends of the absorbent article.
  • the absorbing panels can also comprise transverse channels or embossments along their length.
  • the central panel, or central panels if that is the case, are provided with transverse channels. That configuration increases the available surface area for fluid absorption and minimizes the random wrinkling of the absorbing panels (which would otherwise occur during the use of the article and could eventually favor leaks).
  • the women's napkins of the invention are in a especially preferred way provided with wings or borders that extend laterally from the side edges of the article—they are elements known by those skilled in the art and their purpose is to assist the attachment of the absorbent to the external face of the region between the legs in the user's panties. It is known that said wings are side extensions of the top layer and/or coating layer, eventually comprising absorbent material.
  • an alternative of the present invention foresees that the adjacent absorbing panels to the side edges of the absorbent extend and run partially or fully inside said borders, whose upper and lower faces, like the higher layer and lower layer, are respectively provided with permeability and impermeability.
  • the purpose of that conformation is to prevent the absorbent from leaks.
  • about one third of the dimension of the side border adjacent to the connection with the body of the absorbent article, in the transverse direction, is filled with absorbent material.
  • the present invention brings about an additional benefit to women's napkins provided with side borders, that is, the dissipation of the tensions that are generated along the generally longitudinal connection between the side borders and the body of the woman's napkin.
  • the side borders are provided with adhesive regions to promote its attachment to the external surface of the region between the legs in the user's panties. That attachment is subject to tensions which grow stronger as the longitudinal ends of said ends connections are closer, so that the movements of the user nullify said attachment.
  • the arrangement of several adjacent absorbing panels according to the invention allowing for the movement of a panel in relation to the other, attenuates or even eliminates such tensions and limits the trend “to pull” the attachment region.
  • the channels between the absorbing panels can be continuous, as if creating islands of absorbent material in the region inside the perimeter of the woman's napkin, and in this alternative those that create substantially oblong or ellipsoidal pathways are preferred. That configuration keeps the independence of the absorbing panels in the transverse direction, thus allowing the pivoting of one in relation to the other, and the absorbing core is provided with auxiliary transverse channels in the distribution of the fluid.
  • the woman's napkin of the invention can comprise any other elements known in the state of the art, like deodorants, ion exchanging resins, superabsorbents, zeolites, multiple adhesive regions for attachment of the article to the user's clothes, additional layers for spreading the fluid, etc.
  • the central absorbing panel or panels is/are not provided with adhesive regions.
  • the central absorbing panel or panels is/are not provided with adhesive regions.
  • only the lower face of the side absorbing panels is provided with adhesive regions. That alternative embodiment allows the central panels to move more freely, therefore bringing about a better conformability, and higher dissipation of tensions, the result of which is a better attachment of the napkin to the user's underclothes.
  • the women's napkins encompassed by the invention can have any thickness, from a few millimeters in the thinnest ones to two or more centimeters in the thickest ones.
  • the pivoting effect of the invention has been found to be more pronounced in thicker napkins, for thicker panels are less flexible than thin absorbing panels.
  • FIGS. 1, 2 and 3 attached hereto show the same preferred alternative embodiment of the invention, wherein FIG. 1 is a top view of a woman's napkin, FIG. 2 a cut view of FIG. 1 along transverse line AA, and FIG. 3 is another cut view, but with the absorbent article in use.
